In order to solve the problems such as difficulty in adding mineral fiber, difficulty in feeding, inaccurate measurement and dust pollution caused by adding powder in the process of using mineral fiber by plastic industry, and to meet the needs of injection molding and blow molding customers for plastic reinforcement materials, based on the technical accumulation of mineral fiber with high length-diameter ratio, the company developed the mineral fiber stiffening reinforcement masterbatch.
Mineral fiber reinforced masterbatch has the characteristics of good fiber retention, easy dispersion, good fluidity, wide application range and excellent performance. It can meet the technological requirements of extrusion, injection molding and hollow blow molding, and is suitable for different thermoplastics such as PA, PBT, PP, PE, PVC, ABS, etc. It can improve the strength, rigidity and heat resistance of products, and has obvious economic benefit for reducing the shrinkage rate of the product, improving warpage and processability.

Remark | 1. PP resin is made of copolymer polypropylene J 340, and mineral fiber reinforced masterbatch is made of mineral fiber coated with modifier for polyolefin substrate; 2. Mineral fiber reinforced masterbatch significantly improved the bending strength of PP, but had little effect on tensile strength and impact strength. | ||
